TO ALL WHOM IT MAY CONCERN: i

Be it known that I, Anvil? B. CLARK,-of Richmond, in the county-of Waynmtand State oi' Indiana, have-V invented a new and useful' Improvement in Apparatus for Driving or Setting I'sts; and I do hereby declare the following is a full and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in' which- Figure 1 is afperspectifve view of a wagon and attachment.

Figure 2 is a screw-lever and hase.

Figure 3 is a hand-beetle for driving.

The same letters in the different figures relate to corresponding parts of thefnvention.

My invention consists in'driving or setting posts by the application of power from the force of gravity from the weightof a wagonlor any vehicle drawn by horse-power, thrown upon the post hy means of leverclamps, screws, and hand-beetle.

'.Io enable others skilled in the art to m'ake and use my invention, I will proceed to describe its construction and operation.

Fig. 1. A A A represent a common wagon.

B B represent lever-clamps extending from the front axle-tree to the rear ofv said wagon. v C represents centre-beam or lever so connected with lever-clamps B B, at the front axle-tree,a`s to allow said lever-elamps B B proper niotion for clamping-post. Said heam or lever C` is attached to both axle-trees or parts of said wagon prepared for the same.V i

`D `represents screw passing through lever-clampsB B. 1

E represents post, withrtlle lever-clamps B B attached to the saine by screw D moved by lever J.

`F represents base of hoisting-screw G, which is moved by its lever H.

Irepresents socket-plate firmly attached to eentrebeam or lever C.

Fig. 2. F represents base of hoisting-screw G, which is moved by its lever H, and for convenienceit may #be detached, as shown in said iigyire.4 v

The power for hoisting or raising said wagon s applied by screw G, moved by its lever H against plateI under centrebeam or lever C. Thnsthe rear en'd of wagon may be raised to proper ,height,'when the leverclamps B B are attached to said post by screw D, moved by its lever J. Then screw Gr is turned back to its lowestpoint, thus throwing the whole weight of the rear end'of wagon and contents uponsaid post. After.

driving said post with hand-beetle, asshown in iig. 3, the raising of said wagon may'be repeated, if necessary, until said post is settled to its proper depth. Y I* Said apparatus may be detached from wagon any time, whenever the sameis needed for other purposes. Having thus fully described my said invention, what I claim, and desire to secure by Letters Patent, is- V1. The device, constructed` substantially as described, and arranged upon a wagon in such a manner as to .throw the weight of the vehicle upon the post, as and for the purpose set forth.

2. Theconnbination of lever-clamps B B, centre-beam or lever C, screw D, with its lever J, hoisting-screw set forth.'
